use "su -l"? this is on FreeBSD 6:
By default, the environment is unmodified with the exception of USER,
HOME, and SHELL.
...
-l Simulate a full login. The environment is discarded except for
HOME, SHELL, PATH, TERM, and USER. HOME and SHELL are modified
as above. USER is set to the target login. PATH is set to
``/bin:/usr/bin''. TERM is imported from your current environ-
ment.

su (coreutils) 4.5.3 on RHEL3 behaves exactly the same.
